FASTENING DEVICE FOR, ENVELOPS, BAGS, BOXES, AND OTHER ARTICLES.

Specification of Letters Patent.

Application filed January 12, 1912. Serial No. 670,908.

To aZZ whom it may concern:

Be it known that we, VVILLIAM JOSEPH and WALTER LINCOLN JosnPH, subjects of the King of Great Britain, residing at- Highgate, London, England, have invented certain new and useful Improvements in Fastening Devices for Envelops, Bags, Boxes, and other Articles, of which the following is a specification.

According to this invention, we construct the fastening device in a special manner and from two members.

Our invention will be clearly understood from the following description aided by the annexed drawings, in which Figure l is a collective view of the three pieces forming one member, each piece be ing shown separately in plan and side elevation; Fig. 2 is a vertical sectional view showing the aforesaid pieces assembled and attached to a piece of paper; Fig. 3 is a top plan and Fig. 4 an under plan of the completed member; Fig. 5 is a plan of the other member; Fig. 6 is a plan view and Fig. 7 a vertical section of a modification of the first-mentioned member; and Fig. 8 is a vertical section and Fig. 9 a plan view of the members shown in Figs. 5 and 6 connected together.

One member, Fig 2, comprises a dished piece a, formed with projecting peripheral prongs Z) and provided with a U-shaped interior pocket that reaches from the top thereof slightly past the center. In the construction shown in Figs. 6 to 9, this pocket, which is indicated by the reference letter a, is formed by stamping or pressing out piece a, but it may be produced by providing a plate (Z, Fig. 1, having a U- or equivalent shaped opening 6, that is placed inside the dished piece a; the portion f of the piece a directly adjacent the mouth of the U-shaped opening 6 or recess 0 being cut away or recessed. In the dished piece a is also positioned a disk 9, Fig. 1, having a down-- wardly-extending spring tongue h projecting between the plate 03 and the inside of the said piece a into the pocket above referred to; a lip z is formed on the edge of the disk 9 directly above the tongue h, which lip projects upwardly through the cut away portion f of piece a. The dished piece may be round, oval, square or of other shape, and, if round, the plate and disk are and (Z to prevent them from turning, or by stamping the dish a and disk 9 with tongue 7b in one piece; in the latter instance, the two can be folded together. This member of the appliance is secured by the prongs b to an envelop, box, bag or other article. The other member is composed of a plate of metal Z, Fig. 5, suitably shaped and provided with prongs m'and ribs n for connecting it to the fiap of an envelop, Fig. 9, lid of a box or the strap of a bag or folding part of an article, and such plate Z is provided with a depending tongue 2) having a turned-up edge (1 at its lower end and a clown-turned hook 9* adjacent its upper end. The two members are connected together by passing the tongue p of the plate Z into the pocket in the interior of the other member at the cut away portion f, the turned-up end 9 of the extending strip engaging the spring tongue h as shown in Fig. 8, which latter holds it firmly and without fear of its being removed, while at the same time the hook o of the plate Z engages the lipc' and prevents the spring tongue Zr being operated upon to release it from the tongue 79. Thus by this construction it is impos sible to unlock the two members and any attempt to remove them from the article to which they are attached will be at once seen by reason of one or the other of the members being torn from the article.

The dish-shaped member, as also the other member, may be ornamented or lettered in any desired manner.

We claim as our invention:

A fastener of the class specified comprising a pair of interlocking members, each of which is provided with means for attaching it to the article to be fastened, one of said members consisting of a dish part provided with a downwardly-extending substantially U-shaped pocket opening at lts top through the edge of said part, and a disk connected to said dished part and d1sposed at the back thereof, said disk belng provided with a depending sprlng tongue projecting into said pocket and w1th an upstanding lip arranged d1rectly above sald tongue, the other member consisting of a plate provided with a dependlng tongue 1ntroduced into said pocket between the body of said dished part and the firstnamed set our hands in presence of two subscribing tongue, the second-named tongue being pro- Witnesses. vided adjacent its upper end with a down- WVILLIAM JOSEPH. turned hook engaged with sand 11p and having its lower end upturned and engaged VALTER LINCOLN JOSEPH With the lower end of said first-named Vitnesses: tongue.
